Abstract (en)
[origin: US4260593A] German published patent application 2,710,399 discloses a process for the manufacture of ammonium sulfamate involving introducing sulfur trioxide and ammonia into a pressure vessel containing a melt that mainly consists of ammonium sulfamate and ammonium imidosulfamate, while maintaining a molar ratio between NH3 and SO3 from 1.5:1 to 1.99:1. It has now been found that the pressure vessel is suitably released from pressure for a short period of time after prolonged reaction times to discharge thus the main quantity of the collecting inert gases.
